That is one of the best ideas I have ever heard of for a ROB mod. Imagine taking it a step further by making a ROB security monitoring system to monitor your gameroom or anything else you wanted to keep an eye on. You could even set up a network where you could log in and activate ROB through a remote location using a laptop to conduct surveillance through ROB'S eyes. Modify the base to accept left/right movements to turn his head, and add an additional servo in the head for up/down movement. You could wire up an NES gamepad for additional functions such as activating a siren or motion detector since ROB is capable of button inputs. The possibilities are endless.
